DISK WHEEL.

Application filed September To all whom it may concern:

Be it known that I, DAVID ll. BELLAMURE, a subject of the King-of Great Britain, re siding in the city of New York, borough of Manhattan, county and State of l\'ew York,

' highly ellicient, strong, durable and relative run which has become rusted in ly light construction, possessing all the advantages of both demountable wheels and wheels that have demountable rims, although free from the disadvantage inherent to both of these types.

As disk wheels are now-generally constructed, they are of two distinct types, namely, those wherein the heel is adapted to beremoved from the vehicle when it is desired in change a tire on the road and those wherein'the wheel remains upon the Vehicle and the tire is mounted upon a demountable rim, which may. be positioned Dn or removed from the wheel, in the event 0t puncture or blow-out.

Demountable wheels are very satisfactory inuse, but occasion considerable labor in changing and, accordingly, the demountable. rim is most preferrml, because of easier and less laborious task required -r the changing of a tire on the roadand, furthermore, because of the fact that it is less expensive and more economical to carry an extra demountable rim than an extra wheel or two.

7 Aside from the question of expense and labor, however, both the den'iountable wheel and demountable rim types have-ifurtherdisadvantages well-known to the motorist.

For example, a demouruahle rim is maintained in position upon the folly of the, wheel usually by means oi bolts or clam which become cakcd with mud and rusted to position, so that ii a tire is not changed for several months, it becomes extremely diflicult to make. the change when the oceasion requires, and even though this change may be made, it is a very dirty and laborious task to pry oi? of a \VULPl a demountable the place and which is called and covered with mud.

Withthse considerations in mind, it is 4, 1920. Serial No. 408,250.

the prime object of the present invention to pros ide a wheel which not only possesses the characteristics hereinbefore enumerated but one which may be readily changed on the road without necessitating the prying otl of a demountable rim or the retrieval of the wheel itself. The present invention, liguratively speaking, may be classilied between :1 dcmountable wheel and a demountable rim since, while it is truly neither, it accomplishes the functions of both.

In the preferred practical mar-ner o'fcarrying out the present invention, the rim of the wheel is spaced from the hubby one or" more disks, which disks are divided into inner and outer sections which are demountably associated with one another, so that the outer disk section or sections may ,be removed from the inner disk section or sections, for the purpose of permitting the rim and outer disk section or sections to be demounted or removed from the inner disk section or sections. The advantages of such construction are many, and it will be apparent-that, aside from those hereinbefore enumerated, such a construction not only decreases the'weight at the circumference of the wheel through the elimination of a telly or a, telly band and its securing adjuncts, but also results in a general reduction of the weight of the wheel throughout. Furthermore,when it is desired to demount a tire on the road, the mechanical devices which normally maintain the parts in an assembled relation are so removed from the tire that they are not apt to be caked with dirt ormud, nor so apt to be rusted in place,

as in the case with demountable rims. Ae-

cordingly, the change may be efi'ected more readil v-, with less labor and more expeditiously than heretofore possible with demountable Jrims. Moreover as only the outer portion of the wheel is demountable much less labor is required to change a time on the read than would be necessary for the substitution o'l 'amentire wheel.

Features of the invention, other than tho; specified, as well as the advantages then oi will be apparent from the following specification and claims when .read in con junction with the accompanying drawings;-

In the drawings, I have illustrated one practical embodiment of the invention, but

I wish it understood that the showing therein made is for the dpurpose of illustration. only and does not efine the limits of the invention. I

Figure l is a central section of a wheel constructed in accordance with this invention.

Figure 2 is a face vview of the wheel shown in Figure 1.

Figure 3 1s a section perspective of the wh 1 showing the manner of demounting the emountable portion thereof.

Figure 4 shows a slightly modified form of Wheel section.

Reterring to the drawings, A' designates the hub of a wheel, and B the rim. The hub may be of any desired type, and may be of the kind commonly employed on the wellknown wooden wheels. In fact, the wheel of this invention is particularly adapted to be associated with the hub of a wooden wheel by merely removing the wooden spokes, l'clly, etc., from the hub and bolting the Wheel of this invention in place upon the en wheel. The rim B may be of any wellknown type or characteristic, but is preterably of the simple conventional form shown in the drawings.

The hub A is spaced from the rim 1% by means of one or more disks and, in accordance with the present invention, this disk or disks-are divided into inner and outer sections, which are detach-ably associated with each other. in a specific form of wheel shown, the inner disk sections are two in number, designated in the drawings as G and 1). The disks C and I) are adapted to be bolted to the flange a. of the hub, by means of the usual bolts (1., and a spacer or liller E is positioned between the disks C and D irectly adjacent thc hub, so as to space them apart for the purpose of lending lateral strength to the construction. The spacing means E may be in the form of an annulus.extcmliug entirely around the hub or nay consist of several small blocks through one of which each of the bolts (1. passes, for the purpose of lirmly securing both of the disks C and l) to the hub.

For the purpose of illustration, a 1' *ar wheel is shown in Figure 1, and with such rear wheel is associated a brake drum l, which is adapted to be mounted 01. the wheel by the same bolts a which secures the disks to the hub.

The disk (l is preferably slightly dished in a lateral direction, while the disk l) is preferably dished to a greater degree, so as to render the same a substantial bell shape, as shown, for the purpose of imparting slight radial resiliency to the construction, as well as sufiicient lateral resiliency, to fake rip sudden lateral shocks or strains to obviate disruption or bending of the construction.

hub heretofore associated with the wood- Both the disks C and D are the same diameter, which is of a diameter prclcrably appreciably less than the inner diameter of the rim 1), and, in practice, the outer peripheries of said plates 0 and l) are preferably welded together, either through a continuous weld or by spot welding, although they may be bolted or riveted together, or may if desired, be left unattached to one anot er.

The outer disk section or sections is shown in Figures 1, 2 and 3 of the drawings as one in number and is designated by the reference numeral G, while in Figure l, two such sections are shown, the second section being designated G. When either one of two sections as described is employed, it is secured to the rim B by' welding, riveting, bolting or otherwise, so that the rim is permanently secured to such outer disk section and either or both of said sections are preferably dished, as shown, so as'to bring their inner periph ries into substantially 1h same plane as the outer peripheries of the inner disk sections 0 and .1). In practice, the s ngle outer disk section l), as shown in Figures 1 to 3, 1 preferably employ on pleasure cars or light tracks, but for heavier duty, the construction of Figure 4 showing the extra section (1" may be used. in either event, the rim B with the outer section or sections permanently secured thereto be-' comes a dcmountablc element of the wheel, and means is provided whercby'this clement of the construction may be demountably associated with the remaining portion of the wheel comprising the inner disk sections U and I) and in thehub A.

lVhile the securing means referred to may partake of various forms for the accomplishment of the same end, a pair of clamping rings or annuli and l ma be conveniently and clliciently employed. The ring ll is preferably pern'iancntly secured, although not necessarily so, to thc oulcr margin of the disks C and l) by welding, spot welding, bolts, screws, alike, while such ring is left free from permanent atta hment to the outer disk section or sections. The ring I is normally without attaclnncnt to either of the sections, but may be secured to the ring H, and in clamping relation thereto by means of a plurality of bolts .l which pass through both rings at spaced intervals. throughout their extent, as shown in Figures 1 and Q. The function of the ring. ll and l to collectively form an annular clamp lik'llVPPll which both the inner and outer disk sect ons may be clamped alter the manner shown in Figure 1, for the purpose oi removably associating the demountable portion of the wheel with the relatively permanent portion thereof.

vVith the construction specified, it will be apparent that in the event of a puncture menses .3

or blow-out on the road, the rim of the wheel, togetl'ier with the oute'rsection or sections, may be demounted'as a unit, by simply removing; the nets of the bolts J whereupon the ring I may be withdrawn after the manner shown in Figure 3, and whereupon the demountable section of the wheel may be removed, as also clearly shown in ruoh illustration. This having been accomplished, another demountable sec ion with an inflatedtire in position thereon may be readily and speedily positioned on the permanent: portion of the wheel and secured in pla e through the return of the rin e I to its clamping position, and the application of the nuts of the bolts .l.

It Will be manifest from the 'i oregoing detailed description of the preferred form of the invention that the present wheel eniliodies many features of advantage over those heretofore en'iployed. The use of a demountable disk section permanently associated with the rim, so as to be demountable a unit therewith, has many practical advantages. in the first. place, it economixes in the cost of mainifaeture, for the viding a telly or telly band, in order to obtain demountable characteristics. Moreover, the respective disk sections being of lesser dimensions as to area may be formed economically and with less liability to frat ture than the larger or more expensive disks of the prior constructions. By elimihating the telly, the weight of the wheel at the rim thereof is, accordingly, materially reduced, thereby minimizing gyroscopic disadwu'ita 'es of wheels which are heavily weighted at their rims.

The use of the construction, which may be adapted to the hubs otthe wooden wheels, is also of marked practical ad vantage, since it enables a (:U' owner having a car with wooden wheels to r adilv change to the disk wheel with minimum expense through the use oi" the original hubs, whereas it new hubs were required, additional expense would be entailed and a proper lit w th the axles and bearings would at times be ditii cult.

The (it-mounting of the tire on the road is much simpler with the present invention than. with either of the demountable rim or dimioun-table whee], since it is only necessary to remove the nuts oi the attaching bolts and the bearing between the clamping parts is uch that sticking will not be encoui'iterml in the dci'nouutinn Hi the pa rts. hor will the exertion of great power he required to position the new deniountable section in place. lfiurtliermore, the operator will worl; on a portion ot the wheel which is not so apt to .r-cumulato mud, and. the job will be cleaner and less d tasteful.

in practice, l find that the employment -son that it obviates the necessity of pro-' of cooperating clampingrings H and I give very good results, although, if desiredihis ring, may be eircumterentially broken up into sections, so as to lornrrelatively short clips at each bolt J, without departing From the spiritoi' this invention.

In order that proper driving connection may be had between the inner and outer disk Sections, 1 preferably provide the ring ll with short lugs extending in a lateral direction, and form in the ring I juxtaposed holes 2', so that when the outer dish sect ion is brought into position the pins or lugs will enter the holes and lock the sections together against circumferential movement relative to one another, so that the driving ot' the wheel is not depending entirely upon friction. These lugs, however, may be omitted. is desired.

Another feature of advantage inherent in the present wheel is the fact that l preferably form a recess in one of the outer disksections g, during thestamping thereof, and so shape this recess (9 that the tire nipple may project thereinto, after the manner' shown in dotted lines in Figure 2, thereby enabling the tire to be readily inflated i'rom the outer face of the wheel. in practically all disk wheels, the inflatingo'l' the tire must be accomplished from the inner face of the wheel. which renders the same very inconvenient and dillicult to carry out.

Many advantages other than those specifically referred to will be apparent to those skilled .in the art from a reading of the. foregoing specification, but it may be here further noted that When the outer wheel section is removed, the. brake drum and band of the rear wheels are readily accessible for repair or adjustment without necessitating the actual removal of the brake band or drum. Manifestly, this feature of accessibility has many pronounced advantages not inherent in prior constructions.

In the manufacture of W ZQQlS Of the character specified, it is entirely practical to use stock rims, thereby minimizing the .Costs of manufacture over and above the obvious saving due to the complete absence of a telly section.

The wheel of the present invention, as will be manifest from the foregoing description, embodies many features of novelty, which, when combined in a wheel, result in a striu-ture oi pronounced utility, elliciency and economy.

It will be understood, however, that some of the features described may be used in wheel construction without necessarily employing them all. Moreover, equivalents may be substituted without departing from the spirit or scope of the invention. Accordil igly, the present invention is to be understood as not restricted to the specific details, but is to be construed as broadly novel as is commensu ate with th appended claims.
